【摘要】 对粤东地区“榕江断裂”和“博美—潮安—三饶断裂”的跨断层形变数据进行整理。在形变趋势累计的基础上，进一步对形变速率处理方法改进，解算出跨断层形变异常强度值，并做归一化处理。将形变异常强度指标引入至流动跨断层测量资料的处理分析中，应用于跨断层形变曲线的异常辅助识别，并结合粤东地区震例开展对比研究。分析发现粤东地区地震多发在异常强度高或者由高降低的时段内，对粤东地区的地震前兆识别有一定指示意义。更多还原

【Abstract】 The cross-fault deformation data of "Rongjiang fault" and "Bomei-Chao′an-Sanrao fault" in eastern Guangdong were sorted out. On the basis of the cumulative deformation trend, the deformation rate processing method is further improved, and the abnormal intensity value of cross-fault deformation is calculated and normalized. The abnormal intensity index of deformation is introduced into the processing and analysis of flow crossfault measurement data,which is applied to the abnormal auxiliary identification of cross-fault deformation curve,and the comparative study is carried out with the earthquake cases in eastern Guangdong. It is found that earthquakes in eastern Guangdong occur frequently in the period of high abnormal intensity or decrease from high,which has certain indicative significance for earthquake precursor identification in eastern Guangdong.更多还原
